--- Comment #4 from Aron Budea  ---
The increase of CPU usage started with the commit referenced below. Since this
commit the usage goes up to ~20% for me (4-core AMD CPU, so about 80% of a
core), while in the previous one it's only ~5-10%. I also get the impression
this commit is connected to the current behavior that first a grey rectangle is
shown in place of the menu, and the content is painted after a short, but
noticeable delay.

The interseting thing is that this is a cleanup commit, and it never seems to
have been backported into 5.0. Quite peculiar, I'd say.
Adding Cc: to Markus Mohrhard, please take a look.

[Libreoffice-bugs] [Bug 105633] Increased CPU usage while hoovering over a drop-down menu with OpenGL enabled

[bugzilla-daemon]

https://bugs.documentfoundation.org/show_bug.cgi?id=105633

--- Comment #2 from Telesto  ---
Nearly the same performance behavior can be found when resizing columns in
Calc. Not quite sure if it's a dupe, but seems likely. Found in the same range.
Not in LibO 5.0.0.5 but in 5.0.2.2 and up.

Steps to Reproduce:
1. Enable OpenGL (for best resuls) -> Options -> View
2. Open attachment 130789 (it can also be done without)
3. Click between columns and keep resizing column width.
